The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, Fig. 2, Fig. 3
A kind of board-like heavy oil electric heater is applicable to the following heavy oil of the homemade 250# of heating.Heater structure as shown in the figure.This baffle heater is analysed plate, board-like heater, Pt100 temperature sensor, limiting temperature switch, heat insulation asbestos fibre etc. and is formed by heater housing, edge pipe cast aluminium.
The heating part of heater by three blocks of edge pipe cast aluminium plates 6 and two board-like heater 8 mutual superposition after with bolt 11 and grip the jail and form.Three oil pipes of inlaying between the pipe cast aluminium plate 6 are connected firmly with cutting ferrule joint and oil pipe.Be fixed on the case top lid 3 with bolt 7 after filling up last heat insulation asbestos fibre 5 and positioning sleeve 9 at an upper portion thereof after heating part is formed.Heat insulation asbestos fibre 5 backs are connected firmly with case top lid 3 usefulness screws 13 on housing lower cover 12 back boxings.Heated medium is entered by interface 19, flows out from interface 18 behind the three block casting aluminium sheets of flowing through successively.Two board-like heater 8 usefulness high temperature wires are connected on the binding post 14.Be provided with limiting temperature switch 17 and PT100 temperature sensor 16 in addition in the end of heater.The sensing element of these two temperature control element is arranged at respectively near on the cast aluminium plate of oil-out, and its connecting line is connected on the binding post 15.Accompany a rubber slab 4 between case top lid 4 and housing lower cover 12, rubber slab 4 comes heating part and control section disjunction.Binding post 14,15 is separately fixed on the rubber slab 4.And the limiting temperature switch is by on the support stationary housing loam cake 3.
The heating part quilt of heater two-layer heat insulation asbestos fibre up and down is incubated, and has prevented that effectively heat is export-oriented lost.Heater housing surface temperature through heat-insulation and heat-preservation is no more than 40 ℃.Btu utilization efficient is high.
The heat that heater element produced in the heater is to remove to heat heated medium by the mode of indirect conduction.After the edge pipe cast aluminium plate of heater was heated, heated medium absorbed heat from the cast aluminium plate more then, and the heavy oil in the oil pipe can be heated equably like this.Heated medium heavy oil can not produce localized hyperthermia, so heavy oil just can not gasify or coking.Heater element does not directly contact with heated medium, and the service life of heater element is high.
Referring to Fig. 4
Shown in the figure is heavy oil runner pipe road schematic diagram, and heavy oil stream siphunculus road is to be set in the cast aluminium plate.Between the cast aluminium plate, clip board-like heater.According to the watt level of heater, can design the heat exchange path of different length, just can be in series by two, three or polylith cast aluminium plate.Board-like calandria is also by corresponding watt level coupling one, two or polylith simultaneously.After the heating element heater heating, heat the cast aluminium plate earlier, the heavy oil that flows through passed to heat more on the way by the cast aluminium plate after being heated then.Edge pipe cast aluminium plate detects installing hole 20 by aluminium sheet 1, oil circulation pipeline 2 and oil temperature and forms.
Referring to Fig. 5 and Fig. 6
Board-like heater is designed to flat, and its size is suitable with edge pipe cast aluminium plate.Just in time be lining in during installation between two blocks of edge pipe cast aluminium plates.Board-like heater is a core with the resistant to elevated temperatures micarex 25 of high-insulativity, evenly winds nichrome resistive band 24 with certain specification as heater.Both sides at the micarex that twines resistive band are filled up two-layer insulating mica plate 22 and 23 respectively.The high temperature resistant wire 27 of burn-oning respectively in the both sides of resistive band.Each killinite plate is wrapped up in its appearance after with rivet 26 fixations and is tied up one deck sheet copper 21 and be shell.Heating plate mechanical strength height not only, and processing like this is simple, and reliable operation is easy to use, heats up rapidly thermal efficiency height, long service life.
The oil temperature control is made of a temperature switch and a temperature sensor PT100.Temperature switch is set to the limiting temperature protection.And temperature sensor PT100 sends signal to secondary meter.By the setting of secondary meter being controlled opening, stopping of board-like heater, so just realized control to heater outlet oil temperature.Temperature switch and temperature sensor all are arranged on the edge pipe cast aluminium plate (20 places, position as shown in Figure 4).The set-point of temperature switch and temperature sensor is considerable, because the thermometric of this heater takes is indirect thermometric, is indirect and heating is equally also taked.So point for measuring temperature is not arranged on the position of heavy oil outlet, but the exit position that is arranged at relative heavy oil is more forward, the oily temperature of the relative point for measuring temperature of the temperature of point for measuring temperature position meeting is higher like this, and same outlet oil temperature is also higher with respect to the oily temperature of point for measuring temperature.Just can reach the point for measuring temperature sensed temperature like this can just in time be consistent with the oily temperature of the outlet of heater by cancelling out each other.
The advantage of this electric heater is as follows:
1, heater adopts the formula heating of the long path of tubule, and heavy oil flow velocity in pipeline is relatively fast, and is more abundant with the heat exchange of heater, thermal efficiency height, heat utilization efficiency height.
2, the heater heating chamber is oil pipe, does not have bigger cavity volume. Each one connects with bite type and connects, and can bear bigger operating pressure, does not have the restriction of operating pressure, does not also have the restriction of pressure vessel. Make also very simple and easy.
3, heater adopts the indirect mode, and heavy oil stream is heated evenly in process, and heavy oil does not directly contact with heater, and heavy oil the hot-spot phenomenon can not occur, the phenomenon of heavy oil gasification, coking will not occur.
4, heating element structure novelty because heater does not directly contact with heavy oil, can not cause because of the reason of heated medium the damage of heater. Heater is made simple, reliable operation, use or easy to maintenance, heater long service life.
5, heater adopts the multiplet insulation, and thermal loss is little, and heat insulation effect is good.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model. The technical staff of the industry should understand; the utility model is not subjected to the restriction of above-mentioned example; that describes in above-mentioned example and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope. The claimed scope of the utility model is defined by appending claims and equivalent thereof.
